This little hint might be handy if you are trying to use the Support Debugging Tool to create a non-logging trigger to run some code after a user logs in. The Support Debugging Tool uses a trigger after the Add_Successful_Login_Record global procedure (see more information below) to start its initialization after a user has logged in. Part of this process is starting triggers marked to Automatically Start on Login.
